Intra-Aortic Balloon Counterpulsation in Patients With Acute Myocardial Infarction Complicated by Cardiogenic Shock - The Prospective, Randomised IABP SHOCK Trial for Attenuation of Multi-Organ Dysfunction Syndrome

Patients undergoing percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) with cardiogenic shock (CS) are often treated with Intra-aortic balloon pump counterpulsation (IABP) although the evidence to support this is limited. We conducted a prospective, randomised clinical trial, of IABP as an addition to PCI centred therapy, in patients with AMI complicated by CS.

45 patients with AMI and CS undergoing PCI were randomised to care with or without IABP. Over 4 days, APACHE II scores, haemodynamic parameters, inflammatory markers and BNP levels were collected to assess the impact of IABP treatment on CS triggered multi organ dysfunction syndrome (MODS).
